Multi-view-field laser radar view field angle calibration method

The invention discloses a multi-view-field laser radar view field angle calibration method, which calculates the view field range of a receiving system based on the change of an overlapping factor along with the change of an included angle between a transmitting optical axis and a receiving optical axis, thereby realizing the accurate calculation of the view field angle of a multi-view-field ocean laser radar system. And inversion of optical characteristic parameters and biological parameters of the water body of the multi-view-field laser radar can be realized. According to the method, field angle calibration and measurement of multiple fields can be realized in a laboratory environment, the problem of difficult field measurement and calculation caused by difficult field diaphragm and focal length measurement is ingeniously solved, the operation is simple and convenient, the measurement precision is high, and the measurement precision is high. And the high-precision multi-view-field angle information is obta
